If you're looking for fancy then skip Tim's. This is not a showplace to bring people that you want to impress. It smells bad, is small and is pretty outdated in the decor. If you're looking for huge portions of homestyle food then you'll find it at Tim's.
There is a bar that greets you when you walk in. I've only been to Tim's for lunch so I don't know what the atmosphere is like at night.
In addition to the regular menu they have a menu board that changes with different specials.
If fresh cut fries are your thing (they are my weakness!) then you need to try Tim's fries.
The pictures don't do it justice, but the portions are massive. Pittsburgh style chicken salad right there, it's enough for two or three meals. You will be taking your leftovers home.
Certainly not healthy food, but once a year or so I like to stop in and indulge.
